BARSIC [14]

Answer:

a.Most bacteria and fungi are harmless and may be beneficial to other living things.

Explanation:

Bacteria and Fungi are two distinct organisms that belong to different class of organisms. Fungi are eukaryotic while bacteria are prokaryotic. Although they both exist in different life forms such as being parasitic, saprophytic etc. most bacteria and fungi species are harmless and may even be beneficial to other living things.

Bacteria and Fungi are beneficial to other organisms in the sense that they form mutualistic relationships with other living organisms. For example, certain species of bacteria helps to fix nitrogen in the root nodules of leguminous plants, while fungi forms a mutualistic relationship with algae called LICHEN where they benefit one another in a way or the other.

Explain mutations and how they can cause genetic disease
nadya68 [22]
Answer:

A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals
called mutagens, or infection by viruses. Germ line mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on.

Mutation has been the source of many Hollywood movies, but it's really a simple process of a mistake made in a DNA sequence as it's being copied. Some of that's just the background noise that DNA copying is not perfect, and we should be glad of that or evolution couldn't operate. But mutation can also be induced by things like radiation or carcinogens in a way that can increase the risk of cancers or birth defects. But it's pretty simple; it's basically an induced misspelling of the DNA sequence.
That's a mutation.


When a variant alters a protein that plays a critical role in the body, it can disrupt normal development or cause a health condition. A condition caused by variants in one or more genes is called a genetic disorder. In some cases, gene variants are so severe that they prevent an embryo from surviving until birth.
